The Soviets captured one of our west coast bases and with it one of our Prism Towers. We believe they may be trying to replicate that technology at a secret Soviet research facility in the Yucatan. A SEAL strike team is standing by, Commander, awaiting your orders.
- Mission briefing

Operation: Sun Temple is the ninth mission of the Allied campaign of Command & Conquer: Red Alert 2.[1]


While the popular opinion was that the Allies have the upper hand in their battle against the Soviet Union (in particular the WarWatch programme), the war was far from over. The Reds still had strength and cunning, enough to tip the scales. The Soviets managed to capture one of the Allies' west coast bases, and a Prism Tower with it. In order to mitigate the increasing Allied usage of Prism technology, they attempted to replicate it, establishing a research base in the ruined Mayan city of Tulum, Mexico in the Yucatan Peninsula.

In order to prevent them from reverse-engineering this technology, the Allies deployed a SEAL strike team to the location, to cut short any attempts to replicate the biggest advantage, the Allied war machine ever had. They were also informed that there could be resistance forces there to aid them in the battle. These forces would be bolstered by other units coming in, and if possible, turn the Soviets' latest attempt of making Prism technology against them.

After the SEAL team arrived on the beach by plane, they headed for the nearby village to free the resistance fighters consisting of a GI battalion, 2 Grizzly Tanks and 1 Nighthawk helicopter loaded with five engineers. While the resistance fighters protect their village, the SEAL Team actually swam their way from the beach they arrived onto a secret entrance at the Ore field of the Soviet base.

The helicopter then brought in some Engineers to help capture the Prism Towers. However before doing that, Tesla Reactors must be captured to power up the weapons before capturing the tower to prevent enemy re-capture. Avoiding the War Miners and Soviet armor plus taking out the infantry, Engineers captured the Tesla Reactors, before two of them infiltrated the Prism Cannon pyramids.

Since the Soviets attempted to replicate the Prism technology, the Prism Towers demonstrated their power to them by destroying most of their forces and virtually cleaned up the base. Once the base was fully captured or destroyed, the mission was accomplished.

It is advised to destroy the War Factory to persuade the enemy to focus on infantry attacks, something the SEAL team excel at. By default the Soviet Commander will not build an additional or replacement factory. The remain of the armored vehicles can be lured into the Prism Cannon for safe disposal. Base defense structures can be cleared by Nighthawk Transport or recapture the facility to construct V3 Rocket Launchers. The base is littered with ammo and fuel dumps, good for some job on the fireworks. Should the Commander choose to recapture the base, he/she will be advised to capture the Barracks and use economic support first (similar to Dark Night).

The capture of the Soviet research base meant that the Allies held a foothold in Soviet-controlled Mexico and the Prism technology was safely back in Allied hands. However, not all is lost to the Soviets as the refined designing later is incorporated into Cosmonaut suits (used in To the Moon). Soon the Allied Commander and General Carville were requested for assistance by Germany in the wake of the Soviet invasion on the country, and endangering Professor Einstein's safety.


  • The mission begins with elite Allied SEALs being dropped in by plane.
  • The SEAL commandos rescued resistance fighters.
  • Engineers of the Allied Nations are brought in to capture the Tesla Reactors.
  • The base is either captured by Allied engineers or destroyed by the SEAL team.
  • Two Engineers capture the Prism towers.

Valuable assets[]

  • A Tech Airport on the top-left hand corner of the map.
  • The Prism Tower mechanism is constructed on the temple ruins. Therefore enabled to be captured. The Prism machine here has been powered up, courtesy of Soviet engineering. As the result, a single tower here can conveniently defend itself better than the ordinary Prism Tower, being able to fire more quickly and effectively against the Soviet infantry and armor that come into range.
  • The village in the center of the map contain several "freedom fighters". Liberate them and they will assist against Flak Tracks (Navy SEAL's major weakness).
  • Capturing or destroying the Prism Towers will grant the player two SEALs and one engineer for each tower.


Tulum in yucatan peninsula

Tulum's actual location on the Yucatan Peninsula

  • In the beginning briefing cutscene, an aerial view of Tulum was supposedly shown on one of the monitors. However, the visual was actually an aerial shot of what appeared to be the Mayan city of Ake.
  • In the briefing cutscene, the monitor shows Tulum as being located in the northern area of the Yucatan Peninsula. However, it is actually located in the east area of the peninsula.
  • After the player captures the Airport, Soviet engineers will come out of the barracks to capture it, this can still happen even if the barracks is destroyed or captured.
    • This is because the Engineers are spawned via map triggers, not built regularly; Soviet Engineers are actually unbuildable in this mission.
  • Despite the missions name, Tulum does not actually contain any ruins or temples dedicated specifically to the Sun.
  • Strangely enough, the in-game models for structures as well as the overall location of the ruins are actually accurate to their real-world equivalents.
